This fish is called arapaima, also known as walrus fish. Adult fish can reach 2-6 meters long and weigh up to 200 catties, and are remnants of ancient freshwater fish, which are presumed to have appeared as early as 100 million years ago. Although this freshwater fish is very large, its IQ is a little insufficient, and it is almost extinct because of it. Arapaima live mainly in the rivers of South America. It inhabits the slow-flowing stretches of natural lagoons and Amazon rivers, feeding on small fish, but occasionally preying on snakes, turtles, frogs and insects, and even on small crocodiles.
Arapaima has a powerful brute force, using its tail as a weapon, it can easily knock down adult males and crush bones to cause internal injuries.
Arapaima is a fish that needs to breathe air, and when the weather is extremely hot, the oxygen content of slow-flowing river water decreases, and arapaima needs to float to the surface from time to time to swallow air to breathe.
Arapaima has a huge economic value, and a tonguefish has an average of 140 pounds of fish meat. In Brazil, indigenous people, with permission from the local government, can hunt a certain number of arapaima for food, but there are strict limits on the number and size of the fish.
Its scales are large and hard, sharpened into claw knives, and have a large and beautiful appearance, often used as an ornamental fish. Meat can be made into dried or salt products, is a popular food in the production area, and can be used to replace filing utensils after teeth are dried. In South America, the tongue of the arapaima is ground into a powder, which is mixed with guarana and drunk in water, which is said to kill roundworms.
The first impression of the locals for this fish is "stupid", and fishermen say that it is too easy to catch them, that is, it is too big, and it is more difficult to tow them to the boat.
They are the naturally strongest of freshwater fish, and in the absence of predators, they are fearless of everything, so they become low IQs.
For the smaller arapaima, people just have to wait for it to come up and breathe, pick up a stick and knock them unconscious.
Because they were so stupid and of high economic value, the large number of hunting and killing caused their number to drop sharply and become extinct, and the local government tried to protect them before they survived. In this era of beauty, because of the long and beautiful domestic people buy to be ornamental fish, but raising them is not an easy task, if they are raised indoors, they need to be the same size as the "exhibition tank" of the aquarium, otherwise they need to open a pool in the yard. They are carnivorous fish, and from juvenile to adult fish, animal bait must be fed to feed the active small fish optimally. You can't afford to buy it.
